BARREL-PACKING MACHINE.

Specification of IiettersPatent.

Patented Nov. 24;,v 1908.

Application filed April 21, 1908. Serial No. 428,375.

pmg cases which are filled with granulated,

or pulverized material, and has for its. purpose to. provide for theuniform hammering or application of pressure to the materialas the latter is placed in the case. Tothis end we construct the machine with a yielding support for the barrel. or other receptacle,

and poundthe materialas it is fed thereinto, by one. or more plungers, the resistance offered by" the support to theplungersbeing the particular case. 7

The invention further includes meansfor compensating for the weightof: the material on the-support as it is placed in the barrel, such that the impact of the, blow on the material will be approximately the same throughoutthe packing operation,

Reference is to behad to the; accompanying drawings forming a part of this specifi: cation, in which. similar characters of. reference indicate corresponding parts in both vlews.

Figure 1 is a side elevation of the preferred form ofv our invention complete; and Fig. 2 is a front elevation of the same, partly in central verticalsection.

The machine inits preferred embodiment comprises a framewhichconsists of a suitable base 5, side frames 6 rigidly'attachedlto the base, a top 7 connecting theupper ends of the side frames together, and; a cross-bar 8, rigid with the side frames intermediate their length Projecting-upwardly from. the base between. the side frames 6, at opposite sides of the'machine, are fixed guides 9, preferably in the natureof vertical: shafts. Between the frames 6- is slidably mounted, on the guides 9, a box support 10, forthe barrel or other receptacle to be packed, having its frontopen, as shown-in Fig. 2, and provided with an annular raisedportion or plate 10. on its bottom for centering the barrel and supporting'its bottom head. To each corner of the. box support: is attachedaline. or cable 1.1,.which, at the rear of the machine, asses over sheaves 12 journaled in the head and thence passes to the front of the machine Oversheaves 18, as do the front cables, the sheaves 13. having double grooves for this purpose. The free ends of each set of cables atgone'side of the machine are attached to a weight hanger adapted to carry a number of removable weights 14. Alsoattached at: 0pposite sides ofzthe-box support, near the up.- per edges, are, cables 15, which pass over sheavesilfi journaled adjacent to the base5, andthence ass upwardly and are connected to drums 11 ,fixed tothe opposite ends of a cross-shaft 18. Also fixed to the shaft 18, adjacent to one of the drums 17, is a drum 17, around which passes one or moretimes,

a, cable 15?, having a weight. hanger con.-

nectedtoitssfree:end, to which a number of removablerweights 1.9.. are-adapted to bee pliedh Adjacent to the. other drum 17, t e shaft, 18 is; further supplied with a. handwheel 17 and, a.brake=17, the latter being in thenature of a band passing over a. disk, withthe operating lever for drawingit taut, as clearly shown inFig; 1. shown, is constructed with one or more notches-1 for the-application of a. weight 17.

J ournaled insuitable bearings at the top ofthe' machine is. a cross-shaft 20, having a driving pulley20f, and cranks-.21, fixed to its opposite-ends,.thepins ofwhich are connect.- edwith the insof a. cross-head 22 through the-interme'. lary of connecting rods or pitmen 23; The cross-head 22 is slidably mounted on. the shafts or guides 9, and carries at its center a revoluble head24, preferablysupplied with anti-friction bearings 25. The upper face of' the revoluble head 24 has ratchet teeth 26. circularly arranged. and engaged by a pawl 27 fulcrumed to the outer end of a vpivoted arm 28, the latter being normally retained in an inclined operative positio'nby a spring 29. Through the head 24 centrally. passes a feeditube 30 having a hopper 81 at its upper end,.supported onthe top 7 ofthe frame, andisprovided at its OPPO': site and lower end: with a controlling valve 32, preferably of conical form,.the valve being connected to the projecting arm ofa' segmental gear. 33 by a hanger or stem 34. The segmental gear 33 meshes with a pinion 35 attached to the inner end of a shaft 36.- At tached. to. the. outer; end of this shaft is a small drum 37 about which a cord or cable 38 is. wound. one on more times intermediate This lever, as I suitable handles 39 attached to its free ends.

Rigid with the head 24 are a number of depending plungers 40, which surround the lower portion of the feed tube 30 and project some distance therebelow, and are themselves inclosed by a cylinder or casing 41 attached to the fixed cross-head 8. This cylinder is of a size and shape to closely fit into the upper end of the barrel or receptacle to be packed, in which relation it operates to insure the passage of the material from the feed tube into the receptacle, and prevent the flying of the material due to the operation of the plungers.

In the operation of the machine, the barrel or other shipping case to be packed is seated within the box support, and the Weights 19, sufficient to counterbalance these parts, together with the weight of the material which is to be placed in the barrel, are applied to the weight hangers of the cables 15 The weights 141 are also applied to the weight hangers of'the cables 11 sufficiently to overcome the weights 19, and at the same time to pull the box support upwardly with sufficient force to offer the required resistance to the plungers 10, which of course will depend upon the closeness or firmness the material is to be packed. The granulated or pulverized material is then poured into the hopper 31 and descends through the feed tube at the rate desired, by the operation of the valve 32 by the handles 39. The box support is gradually elevated by the operation of the brake lever 17 until the bottom of the barrel presses against the lower end of the cylinder or casing 41, which, as shown, projects a slight distance below the extreme lower position of the plungers in order that there will be no danger of the plungers striking the bottom of the receptacle. As the pulley 20 is driven, the plungers 40 are reciprocated through the intermediate connecting mechanism and pound or pack the material into the barrel. On each upward stroke of the plungers, the connection between the pawl 27 and spring-arm 28 contacts with the top of the frame and forces the revoluble head 24: around the distance between one or more of the ratchet teeth, thus imparting a step by step revolution to the plungers during their linear movement. Each time a measured quantity of the material passes into the barrel its weight may be compensated for by removing one or more of the weights 19, thus adapting the box support to offer the same resistance to the plungers throughout the packing operation.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. The combination of a support for a receptacle, means for packing a material within the receptacle, variable means normally forcing the receptacle toward the packing means, and variable means normally drawing the support away from the packing means for compensating for the weight of the material placed within the receptacle.
